Be ready for Christ's universal, visible, and sudden return, fearing his wrath and vengeance

"Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it." Matthew 7:24-27, KJV
